The perimeter of a square is 56 cm. what is the approximate length of its diagonal

20

Step-by-step explanation:

To solve this, we have to multiply one of the side lengths by the square root of 2.

Since it is a square, we can deduce that all of the side lengths are equal, and us finding one of the side lengths is as simple as dividing 56 by 4.

56/4=14

Now, multiply.

14*square root of 2 is 19.7989898732 or 20.

The length of the diagonal of the square is 20.

Hope this helps!

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
